Police said Gilliam conspired with two other Bridgeport men to rob the TD Bank at 1111 Post Road E. shortly before 5 p.m. Wednesday, the Courant reported.

Westport and Stratford investigators determined that Gilliam had fled to Brooklyn, and New York City police helped Westport officers make the arrest, the Courant said. He was charged with first-degree robbery, third-degree larceny and conspiracy.

Two suspects entered the bank, with one displaying a black handgun and demanding money, police said. After receiving an undetermined amount of money from the teller, the suspects fled in a vehicle southbound on Morningside Drive, police said.

The car was described as a small black hatchback with dark tinted windows, possibly a Nissan Versa or Volkswagen. Witnesses said the license plate was 213TZV, but it does not match the vehicle, police said.

The suspects were described as black males, each wearing a black shirt, black pants and a ski mask.

While officers were checking the surrounding areas for the vehicle, a Westport Police Detective observed a person matching the description of a suspect walking in the area of Greens Farms Road and Westway Road. As the detective approached, the suspect attempted to conceal himself in the wood line, police said. The detective ordered the suspect out at gunpoint, and he was subsequently taken into custody after evidence from TD Bank was discovered in his possession, police said.

The suspect was transported to Norwalk Hospital at his request for a medical issue, police said. He was later discharged and transported to the Westport Police Department.

The suspect was identified as Lancelot Andrew Supersad, 19, of Bridgeport. He was charged with first-degree robbery, first-degree conspiracy to commit robbery, third-degree larceny, and third-degree conspiracy to commit larceny. He was held on $100,000 bond.

The second suspect was arrest at 1:45 a.m. Wednesday by Westport police detectives, working with Stratford police detectives and the FBI, police said in a statement. Police did not release details of where and how he was arrested.

Anthony Santiago, 20, of Bridgeport, was charged with first-degree robbery, first-degree conspiracy to commit robbery, third-degree larceny and third-degree conspiracy to commit larceny. Santiago was held on $100,000 bond.
